.EYEGLASS-OASE.

Speciflca.tion o! Letten Patent.

Patented Jan. 19, 1909.

T0 all whom it ma concem:

Be it known t et I, Amxsox W. FAR- mxcrrox, of Rande! h, in the county of Norfolk und Stute of %-Iassachusetts, have invented certain new am! useful Improvements in Eyeg 'glassCases, of which the following is a specification.

This invention relates to boxes, und h us particular reference to metal boxes compnsin two members hinged together und provi ed with spring devices for holding the said members in either closed or open position.

The object of this invention is 10 provide a simple und dumble spring connection, gnd one which shall be noiseless in its operatwn.

T0 these ends, the invention' consists in the construction und combination cf arts substantially as hereinafter described und claimed.

Of the accompanying drawings, Figure 1 is a plau view of a box of the pe commonly known es an eyeglass-case, t e lid being open. Fig. 2 represents a section online 2-2 of Fig. 1. Fig. 3 is a view similar to Fi 2, but showing the lid as closed.

im'1lar reference characters mdicate sinnilar rts throu hout the several views.

T e two mem ers of the box comprise the lower or body member 10, und the upper or cover or lid member 11, seid two members being connected by hinges 12, which hinges may be oonstructed in any ordinary or preferred manner.

The member 10 is formed with a lag 13, which ma comprise a. rolled lip suitably formed to e engaged by one end of the link hereinafter described. baid lu 13 is not in alinement with the axis of the inge 12, bat.

Es located below an imagin line connect- 12ng he two hinges 12, as own in Figs.

The cover or lid member 11 is provided mth ears 14 14, which are showu as cum nrising hps stmck up from metal of the cover, and baut as shown, to engage the encls of 2 substantially straight sgrmg 15. Seid sppng p referabl; cc msxsts o a piece of res1hent w1re, hgv1n 1ts extreme ends baut or curved as md1'cnt in Fig. 1, so as to prevent longitudinal movement of the s ring relat1vely to the ears 14. In practice, owever, the ears 14 am usua1ly baut down u'pon the sprmg figmly e1 xqugh toyetain it permanently m 1ts pos1t1on agamst the under side of the lid und paral1el with the line of the hin es 12.

A lin 16, which may consist of a. strip oi sheet metal, is bent at its ends to form a lower hook 17 to en ge the Ing 13 of the box member 10, an an upper hook 18, which embmces the middle portion of the spring 15. Said link is of such length that whether the box be opened 01' closed, the spring will be flexed or under such tension as to constantly exert a. pulling action 011 the 1ink.

As shown in Figs. 2 and 3, the construction of the parts and the ositions or Iocations of the points of attac ent 011 the 1ink to the spring cf one member of the box, und the Ing of the other member cf the box relatively to an imaginary ]ine extending from one hinge 12 tot e other hin 12, is such as to penmt the end 18 of the ink to pass beyond the said imagmary 1ine when moving from the'position shown in Fig. 3 to that. shown in F 2. In other words, a plane intersecting t e oints indicated by 12 und 13 is crossed by t e link when mov1 irom one extreme osition to the other es e box is 0 ned or closed. In passing such Iine or p uns, an imaginary line connocting the two ears 14 is necessarily at u, greater distance from the lug 13 to which one end of the link is attached, und consequently the spring 15 exerts greater tension whn the lmes 12, 13, und 14 aue in one plane laben when the end 18 of the link moves Iao either one of its extreme positions. Therefore, the spr' und the link tend to kee the box close or open, und yet under a yie d.ing ten' sion, so thai: the lid may be quickly snapped open or shut.

Obviously the positions of the parts might be reversed. In other werde, the member 11 of the box nnght be the lower or body member, und the member 10 so formed as to canstitute the eover or lid. Fnrthermore, it is to be understood that I do not limit myself to the particular form of box shown, sinne the invention mny be embodied in other forma .of eyeglass-cases, or other forms of boxes in general.

Having now described my invention, I claim 1d b tw 1. fing i 0x comprising omembers havmg a hinged connection a spring formed of a single piec e 0f res' ient wire secured 120 one of sa1d members, means for preventing longitudinal movement of said spring und a ink connected to the other member und fra to move independently thereof, said link enga 'ng su.id s ring at a int intermediate of t e ends of t 1e latter w ereby the spring will exert a pulling action upon said link.

2. A spring lid box compnsmg two members havmg a hinged connection, one of suid members having ears struck up therefrom a spring formed of vesilient wire the ends of which am fastened beneath said enrs, und a link connected to the other member und free to move independently thereof, said link engaging said sprin at a point iutermediate of the ends of the Tflttl', whereby the spring will exert a pulling action upon said link. 5

3. A spring lid box comprising two unembers havmg a hinged connection, one of said mez nbers having ears struck up therefrom, a sp r1 formed of a single piece of resilient wne mving its ends secured beneath said aus, said ends being bent, und a link coune cted to the other member und engagin smd spring at a point intermediata of the ends of the latter, whereby the spring will exert a pulling action u an the linlc In testimony whereo I have afiixed my sxgnnture, in presence of two witnesses.
